Import where-am-i demo app fix

Call to where-am-i on 32bits platform ends up with following error:
*** stack smashing detected ***: terminated

GTimeVal parameters are glong, which depends on the platform, but
timestamp returned by geoclue is guint64 for both seconds and useconds.
Furthermore GTimeVal is marked as deprecated.
